What could be the cause of a vibrating steering wheel in an Audi 80?

I have noticed that my Audi 80's steering wheel vibrates while driving on the highway. What could be the potential cause of this issue and how can it be addressed?

The most common cause of a vibrating steering wheel in an Audi 80 is an out-of-balance wheel or tire. Make sure to have your tires balanced and rotated regularly to prevent this issue.

It's also possible that there is an issue with the suspension or steering components. Have a mechanic take a closer look to determine the root cause of the vibration.

Another possibility is that the alignment of your wheels is off. This can cause the steering wheel to vibrate and also lead to uneven tire wear. Get your alignment checked and adjusted if necessary.
